Patch Changes

• Add createEffect API for reactive delta-driven effects and useLiveQueryEffect React hook. (#1221)

  createEffect attaches callbacks to a live query's delta stream — firing onEnter, onExit, and onUpdate for row-level query-result transitions and onBatch for the full delta batch from each graph run — without materialising the full result set. Supports skipInitial, orderBy + limit (top-K window), joins, lazy loading, transaction coalescing, async disposal with AbortSignal, and onSourceError / onError callbacks.

  useLiveQueryEffect is the React hook wrapper that manages the effect lifecycle (create on mount, dispose on unmount, recreate on dependency change).
